Basically there is a few reputable 'names' with curacao casinos, which means by license curacao you cant really trust the license, but the operator/owners are reputable people thus not scamming people. Example of this is Bitstarz which paid a winner 2.4 Million out the NEXT day, therefore earning my trust. I have played there a bit myself and got withdrawals of larger sums within minutes.
So when i refer to noname Curacaos, its zero-source-reputation sites that do things like change bonus terms overnight to refuse someone a 5 digit withdrawal. Ive had this happen to a friend and was witnessing the whole start to end, its super disgusting.
